Answer:
768 m²
Step-by-step explanation:
8 x 400 = 3200 cm = 32 m
6 x 400 = 2400 cm = 24m
32 x 24 = 768 m²
The answer is C.0,3 because One of Y equal 0 for X
Answer:

Step-by-step explanation:
see the attached figure with the letter D to better understand the problem
we know that
The segment side AD is the height of triangle ABC
so
Triangles PBQ and ABD are similar by AA Similarity Theorem
The area of triangle ABC is equal to

we have

substitute


Remember that
If two triangles are similar then the ratio of its corresponding sides is proportional
so

substitute the given values



Answer:
-4 and 5
Step-by-step explanation:
4*5 = x(x-1) ; cross multiply
20 = x²-x ; distribute multiplication over subtraction
x²-x-20 =0; subtract 20 from both sides
(x+4) (x-5) = 0; factor
x+4 =0 gives x = -4
x-5 =0 gives x = 5
